Level 5: SCC
|Description||This chapter describes dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. criteriameasure of how well one variable or set of variables predicts an outcome of squamous cell carinoma|

- Scale (rough texture) is present in almost all lesions
- Glomerular (coiled) vesselsThis glossary term has not yet been described.
- Focally distributed towards the periphery
- Diffusely present throughout lesion
- Aligned linearly within lesion
- White circles
- Brown circlesThis glossary term has not yet been described.
- RosettesFour bright white dots or clods arranged together as a square (or a four leaf clover) (seen with polarized lightThis glossary term has not yet been described.)
- Brown dots aligned in a linear fashion
- Strawberry patternReddish pseudo-network (erythema and wavy fine vessels) around hair follicle openings which are accentuated with a white halo appearance seen in actinic keratosisActinic keratosis (also called solar keratosis and senile keratosis; abbreviated as AK) is a pre-cancerous patch of thick, scaly, or crusty skin. (AKThis glossary term has not yet been described.)
- Hairpin (looped) vessels with a white halo can be seen in keratoacanthomas (KA). In KA these looped-vessels tend to be aligned at the periphery.
- Polymorphous vascular pattern composed of dotted, short linear and long linear irregularlinear vessels with multiple bends (serpentine) vessels.
